Automating AWS Agent Registry updates for MCP servers
In short: AWS has published a guide on creating an event-driven architecture to automatically sync Model Context Protocol (MCP) tool schemas with the AWS Agent Registry. Using AWS CloudTrail, EventBridge, and Lambda, this pipeline detects runtime changes and updates the registry whenever an MCP server's tool schema evolves.

What changed?
- 1Implementation of a push-based synchronization pipeline
- 2Automated discovery of MCP tool schema updates
- 3Cross-account event forwarding support
- 4Integration with AgentCore Identity for secure M2M OAuth authentication
Why it matters
Manually updating registries after deploying new tools is prone to errors, often leading to stale metadata and application failures. This automation ensures registry consistency across multi-account enterprise environments, reducing the risk of runtime errors and improving developer trust in cataloged tools.
What it means for AI agents and contact centers
If your infrastructure relies on Amazon Bedrock AgentCore and MCP, implementing this pattern is crucial for maintaining real-time accuracy in tool availability. When testing, prioritize measuring the 5-15 minute propagation delay inherent in CloudTrail management events and ensure your OAuth M2M flow correctly handles the multi-account identity scope.
🧪 Worth Testing
It eliminates manual overhead and prevents runtime failures caused by outdated tool schemas.
